Kim Kardashian And Kanye West Welcome Baby Number Three

Kim Kardashian West and her rapper husband Kanye West have announced their third child on Tuesday, a baby girl born to a surrogate.

"Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl," Kim announced on her app on Tuesday.

The couple thanked the unidentified surrogate "who made our dreams come true with the greatest gift one could give".

They said the baby was born on Monday but they did not announce a name.

Kardashian, 37, and West are already parents to North, four, and Saint, two.

The Keeping Up with the Kardashians reality and social media star has said she decided to use a surrogate after doctors warned of serious health risks if she became pregnant again.

Now that the baby's birth has been confirmed, conspiracy theories are at an all-time high that Kylie Jenner was Kim and Kanye's surrogate.

This, only fuelled by the fact that K-dizzle has been MIA since the news broke she was pregnant in September and "reportedly" went into labour on Monday...

According to Twitter, Kylie was spotted with Kim and Kanye at Cedars-Sinai Medical Center in LA, reporting she had gone into labour.

In hindsight, you could say that she may have just been visiting her new niece BUT the timing couldn't be more coincidental.

Earlier that day, she was spotted near the hospital at a local CVS store...

Khloe Kardashian, 33, also announced in December that she is six months pregnant with her basketball player boyfriend Tristan Thomas, while their half-sister Kylie Jenner, 20, is reported to be expecting her first child soon.

The arrival of Kardashian and West's third child swiftly became on of the top five trending topics on Twitter.
